FOUNTAIN ATTACHMENT FOR PENS- SPECIFICATION forming m of Letters PatentN 0. 762,728, dated June 14, 1904.

Application filed November 17, 1903. Serial No.181,534. (No model.)

Be it known that I, JOHN W. LANGDON, a citizen of the United States, anda resident of Walla Walla, in county oflNallawalla and State ofWashington, have made certain new and useful Improvements in FountainAttachments for Pens, of which the following is :1. Specification.

My inventionis an improved fountain attachment for pens having for anobject, among others, to provide a novel construction which can befilled and emptied through its front end and which at its said front endwill be free from contact with the pen-point, so that the flexibility ofthe latter will in no wise be impaired; and the invention consists incertain improvements and novel constructions, as will be hereinafterdescribed and claimed.

In the drawings, Figure 1 is a perspective view of my invention as inuse. Fig. 2 is a longitudinal section of the attachment on a pen onabout line 2 2 of Fig. 3. Fig. 3 is a bottom plan view of the device ona pen. Fig. 4 is a cross-section on about line at 4 of Fig. 8. Fig. 5 isa side elevation. Fig. 6 is a front elevation. Fig. 7 is a bottom planview, and Fig. 8 a detail perspective view,'of the improved reservoir;and Fig. 9isadetail section, partly broken away, on the same line asFig. 2, but on an enlarged scale, to better illustrate the broadclamping-bearing of the improved device.

By my invention I seek to provide a reservoir attachment formed toprovide a front feed and discharge and so constructed that when attachedto a pen in position for use no part. of the reservoir except that forclasping it in place on the pen-point is in contact with such pen, sothat the latter has a perfectly free action, and its flexibility willnot be impaired in any degree. t

As shown, the improved reservoir A, which may be made of rubber,aluminium, celluloid, or other suitable material, is in the form of anoblong body somewhat flattened in crosssection, as will be understoodfrom Figs. 4

and 6, provided at its rear end with a clasp r at B to bind thepen-point and provided at its front end with the opening G, whichentirely encircles the point of the pen, usually at about the base ofthe nibs thereof, and is free from contact with the nibs of thepen-point, a continuous space being provided entirely around the pen atthe front end of the body A, as will be understood from Figs. 2, 6, and8 of the drawings. The form of the opening C is important, itbeingmodified by the upper and lower lips G and which curve down and uptoward the pen p0int to such an extent as to reduce the width of theopeningC at its middle in order to aid in properly confining the ink incontact with the pen-point, while the side portions 0 of theopening Cwiden out by curving upwardly and downwardly, as best shown in Figs. 6and 8 of the drawings. From Figs. 6 and 8 it will be noticed the body Arounds outwardly both vertically and laterally, in rear of its frontopening C, thus affording sufficient holding capacity for ink, which isboth fed to and discharged from the reservoir through the front openingC, as will be more fully described hereinafter. At its rear end the bodyA is divided longitudinally at D into upper and lower tongues D and Dwhich form a clasp to bind upon the pen-point, as shown in Fig. 2, andare slightly outturned attheir free extremities cl and (i as shown inFigs. 2 and 5, to facilitate the application of the reservoir to a pen,as will be understood from Figs. 1, 2, and 5 of the drawings.

As before suggested, the front end of the reservoir, in fact, allportions of the reservoir in advance of the clasp, are entirely freefrom any contact with the pen-point in order to avoid any interferencewith the flexibility of the point in the use of the same in the ordinarymanner. In order to prevent any parts of the reservoir in advance of itsclasp from coming in contact with the penpoint, l form such clasp with abroad bearing for engagement with the pen in order to hold the reservoirsteadily in the position shown in Fig. 2

of the drawings. lprefer to secure this broad bearing by theconstruction shown in Fig. 9, in which the tongues D and D areflattened, as best shown in Fig. 9 at 1 and 2, to form the broad flatbearing on opposite sides of the pen-point, as is also indicated inFigs. 2 and 5, whereby to prevent any rocking of the reservoir on thepen-point and to hold the said reservoir steadily in the poistion shownin Fig. 2, so thatits front end will not at any time come in contactwith the point of the pen.

In attaching the reservoir to pens the penpointis inserted between theupper flattened tongue and the lower spring-tongue at the rear of thereservoir, and the flattened bearing between the upper and lower tonguesguides the pen-point through the center of the reservoir and out betweenthe upper and lower projecting lips of the front feed-opening withouttouching any part of said feed. This feed is so constructed that whenthe reservoir is attached to the pen no part of the feed end of thereservoir touches the penpoint, an open space being left entirely aroundthe point, permit-tin g perfectly natural action of the nibs and alsothe ready filling of the reservoir with ink through the frontfeed-opening by the usual operation of dipping the pen into an ink-well.This construction also permits the emptying of the reservoir when itscontents have only been partially used with one or two quick downwardmovements of the penholder, enabling the writer to empty the reservoirjust as he woulddischarge the surplus ink from an ordinary pen. It willbe noticed that the front feed is so constructed that its upper andlower lips serve to feed the last particle of ink to the pen-point andto assist capillary attractionin retaining the ink in the reservoir andpreventing the ink from accidentally dropping from the reservoir.

It will be noted that in clasping the reservoir on the pen the lowersection or tongue of the clasp operates as a spring, being narrowrelatively to the upper tongue and opposing the latter by a springing orresilient action and operating to securely hold the reservoir on the penin the use of the device.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The herein-described attachment for pens consisting of the bodyprovided in its front end with an opening for the passage of thepen-point, said opening being formed with upper and lower lips spacedapart relatively in such manner as to avoid any contact with thepen-point, and divided longitudinally at its rear endforming the upperand lower tongues having flattened portions forming broad hearings toengage with a pen-point to prevent any rocking of the reservoir, saidtongues being outturned at their free ends to facilitate the insertionof a pen-point in applying the reservoir thereto.

2. An attachment for pens comprising a reservoir having a body providedat its front end with an opening so formed as to avoid any engagement ofsuch end of the reservoir with the pen-point through which opening inkmay be fed to and discharged from the reservoir and in rear of suchfront opening with means for holding the reservoir on a pen-pointsubstantially as set forth.

3. The combination with a pen-point of a reservoir thereon andconsisting of a body having at its front end an opening forming apassage entirely around the penpoint, and no portion of whose wallscomes in contact with the pen-point, and means in rear of said frontopening for securing the reservoir in place.

4. An attachment for pens comprising a reservoir provided at its frontend with an opening for the ink forming a passage entirely around thepen-point and no portion of whose wallscomes in contact with thepenpoint and upper and lower lips projecting into said opening, theopening on opposite sides of the lips being enlarged substantially asset forth.

5. An attachment for pens comprising the reservoir having at its rearend a clasp having a broad bearing for engagement with the penpoint toprevent any rocking of the reservoir on said point and provided at itsfront end with an opening through which the pen-point protrudes, thesaid opening being so formed as to avoid any engagement of such end ofthe reservoir with the pen-point substantially as set forth.

6. An attachment for pens comprising an outwardly-rounded reservoirhaving at its front end an opening forming a continuous passage aroundthe point of a pen no portion of whose walls comes in contact with thepenpoint and at its rear end a clasp to engage with the pen-pointsubstantially as set forth.

7 An attachment for pens comprising the reservoir having the opposingtongues at its rear end to engage with a pen-point and an opening at itsfront end having upper and lower lips to extend on opposite sides of andfree from contact with a pen-point, substantially as set forth.

8. An attachment for pens comprising a reservoir swelled outwardly atits middle portion and provided at its rear end with a clasp to engagewith a pen-point and at its front end with an opening forming a passageto encircle a pen-point through which ink may be fed to and dischargedfrom the reservoir no portion of the walls of such passage coming incontact with a pen-point when the reservoir is applied theretosubstantially as set forth.

9. A reservoir attachment for pens comgrip a pen and flared outwardly attheir free ends to facilitate the introduction of a pen- I0 pointsubstantially as set forth.
